User-Defined Mode Editing

This is part of an optional software upgrade

Figure UD3 shows the User-Def Edit menu for the BP Test Screen.

From the User-Def menu, pressing F3 (Edit) opens the current selection for editing and

brings up the User-Def Edit Menu.

F1 (Select) moves the highlight to select a parameter for editing.

Left/Right arrow keys also move the highlight to select a parameter for editing.

The Up/Down arrow keys change the value of the highlighted parameter.

F2 (Trim) opens the Trim Menu.

F4 (Enter) saves the changes.

Figure UD4 shows the User-Def Trim menu for the BP Test Screen.

From the User-Def Edit menu, pressing F2 (Trim) opens this additional menu level of

editing.

F1 (Select) chooses Delta Sys, Delta Dia, or the MAP label for editing.

Left/Right arrow keys also move the selection highlight.

The Up/Down arrow keys change the value of the highlighted parameter.

F2 (Trim) returns to the standard Edit Menu.

F4 (Enter) saves the changes.

User-Defined Mode Ranges and Use

This is part of an optional software upgrade

The User Defined parameters can be adjusted over a very broad range. For some

parameters the range well exceeds that of typical NIBP monitors currently available. This

extended range is provided for research and to explore the true absolute limits of an

instrument. We impose few limits on the combinations available and leave it to the user

to decide what is valid for their purpose or physiologically unrealistic.

General range limits:

Systolic range is 20 – 295 mmHg

Diastolic range is 10 – 260 mmHg

Pulse Rate range is 15 – 330 BPM

Amplitude range is 0 – 150 % of our nominal Adult setting

A/N (Adult/Neo) is a label only. The appropriate amplitude for neonatal use must be set

by adjusting the amplitude setting.

The actual value of MAP output is set internally by the rule of thirds and follows changes

of the SYS/DIA settings made by the user. By default this value label is not displayed. It

can be turned on using the Trim menu. The MAP value displayed is a label only. In the

Trim Menu a user can adjust the value displayed to match the expected monitor results,

but can not directly move the underlying MAP point.

When making adjustments a minimum pulse pressure (Sys – Dia) of 10 is enforced.

Attempting to move the systolic value below this spread will push the diastolic down as

well. Raising diastolic operates in similar fashion.

The maximum Trim value range is +/- 25 mmHg for both Delta Sys and Delta Dia. This

range is limited as needed when the Trim would otherwise meet the MAP point or the

end range of the AccuPulse Plus unit.

Fig. UD3.

All User Defined settings will be permanently stored until a user changes them. These

will be retained across a power cycle.

Seq Tab (Auto Sequence)

The User Defined option module also adds some extended functionality to Auto-

sequence while operating in the User-Def Mode. These changes allow the user to choose

any of the 45 User-Def points to define their own sequence.

Under the Seq Tab pressing F1 (Seq Config) opens a new screen and menu to select the

points to use.

User Defined Auto Sequence

F1 (Add) allows the user to add points to the sequence immediately following the current

highlight point.

Fig. UD4.

Up/Down arrow keys change the value of the highlighted sequence location.

Left/Right arrow keys move the highlight across the sequence list.

F2 (Del) will delete the currently highlighted point from the sequence.

F3 (Save) stores the currently displayed sequence for use.

F4 (Exit) leaves without saving any changes.

Note that points to run do not have to be adjacent in the User-Defined Mode list, nor in

any particular order, and a single point can be used more than once. (Example: 1, 18,

43, 44, 7, 32, 18, 32 )

All other Autosequence functions remain unchanged from the standard operation.

Mot Tab (Motion Artifact)

This is an optional software upgrade

The Motion Artifact option provides a way to mix noise into the normal pulse patterns.

While in BP Test mode F1 switches Motion On and Off.

Figure M1 shows the Motion Tab screen.
